Increase efficiency and longevity of your Downstream Injector
If you're using a General Pump Downstream Chemical Injector, you may want to consider adding a Skunk Check Valve to your setup. Not only does it help prolong the life of your injector, but it can also improve the strength of your chemical mix.
How is the Skunk different? Hastelloy... What is Hastelloy? Good question...
HASTELLOY C-276 is a nickel-chromium-molybdenum alloy with universal corrosion resistance unmatched by any other alloy. It has outstanding resistance to a wide variety of chemical process environments including ferric and cupric chlorides, hot contaminated mineral acids, solvents, chlorine and chlorine contaminated (both organic and inorganic), dry chlorine, formic and acetic acids, acetic anhydride, sea water and brine solutions and hypochlorite and chlorine dioxide solutions. -
Product technology
TLDR: The spring inside the Skunk Check Valve is made of Hastelloy, therefore it's highly resistant to corrosion.
This is a special upgrade exclusive to our model.
What Downstream Injector Does The Skunk Check Valve Connect To?
For the best results, we recommend using the 2.1 or 2.3 General Pump Hi Draw Injector in conjunction with the Skunk Check Valve. This injector is the one that we use on all our machines and has proven to be reliable and efficient. It is also the only chemical injector that the supplied adaptor will interface with. Attempting to install it on another type of injector may result in breaking the fitting and rendering it unusable.
Will This Check Valve Give Me A Hotter Mix?
In addition to increasing the longevity of your injector, using a Skunk Check Valve can also help improve the effectiveness of your chemical mix. With a stronger chemical mix, you can clean porous surfaces, such as those with black algae stains, faster and more efficiently.
We've had a few prototypes in the field for months, still running strong, and the reports are its delivering a hotter mix than any stock downstream injector could. We don't have the exact numbers yet, but we will be running tests in the coming months and will post them here. The mix is definitely hotter, and the Skunk Test Pilots that are the most vocal about loving this valve are using 8 gpm and 10 gpm machines. The volume these larger GPM machines put out dilutes a stock downstream injector mix heavily, and the Skunk Check Valve has shown to add back the concentration of chemical they lost.
How to Use Check Valve for General Pump Downstream Chemical Injectors
To use the Check Valve, simply follow the instructions provided in the video below.
*These check valves will last longer than a normal downstream injector, but like everything Im sure will eventually need to be replaced. That being said, we are flushing them out multiple times per day with the Smart Stream so ours are taken care of. They are not trashed and not left to soak in hot bleach. I recommend you flush yours as well.
*There is no warranty for anything that touches bleach, if it breaks, buy another one.

Great longevity
"On season two with this, I have a 3 way pvc ball valve so I can flush with water coming from buffer tank. I flush it well after each day, thing has been a workhorse for me."
Great quality.

"Went all 2024 season with one skunk valve without changing it out! Anyone who's used downstream injectors knows that you change them frequently and it's always right in the middle of a job when you're up on a ladder in the back of the house it's always the most inconvenient time! Skunk valves are dependable! I know this from experience and I'll never be without a couple of them"

Q&A
- Would this work on a dual barb injector on the bleach/SH side along with a normal barb for Surfactant/soap on the other?
- It will pull chemical as long as the injector is a GP injector. The treading must be General Pump. (GP)
- Why do I need this? Does it prevent SH feeding back into the pump? And do I remove anything from injector with this installed?
- All downstream injectors are placed after the pump so you would never have an issue with your first question. Secondly yes you have to remove the barb on a normal injector with the ball and spring as well then you add the skunk check valve to the injector where you removed the original barb. Lastly by doing that your injector will last much longer. Most issues with downstream injectors come from corrosion through the ball and spring portion. You also get a stronger mix by using the skunk check valve.
